PHONOGRAPH.

Specification of Letters Patent.

Patented Aug. 1, 1911'.

Application tiled September 1, 1910. Serial No. 580,107.

Locust Corner, in the county of Clermont and State of Ohio, have invented certain new and useful Improvements in Phonocatlon.

The invent'on relates to attachments for phonographs y means of which both disk and cylinder records can be used on cylinder machines. By the use of these devices both styles of records can be played with equal convenience and very little time is required to make the change when the alternate style is desired.

The playing of disk records is accom- 4 plished by the use of a jointed bracket which is adapted to support a disk turn-table, suitable gearing to impart motion from the phonograph driving mechanism -to the turntable 'and a diskf record reproducer which can readily be interchanged with the cylinder record reproducer. But, when cylinder records are to be used the turn-table is removed and the jointed bracket is folded back out of the way.

A preferred form of the invention is illusv trated in the accompanying drawings, forming part hereof, in which- Figure 1 is a frontrview of a cylinder phonograph, showing the devices in use with a. disk record; Fig. 2, an end view of the same, showing the jointed bracket in its .prone position in dotted lines; Fig. 3, a perspective view showin 'the machlne in use with a cylinder recor Fig. 4, a section on line 4-4, Fig. 2;'Fig. 5, a top. view of a portion of the base of the phono raph; Fig. 6, a View of the goose-neck, s owing the split tube, 'formin V part thereof, inthe positlon to withdraw't e reproducer; and Fig. 7,

a similar view, "with y parts broken away,

' showing the goose-neck connected to the reproducer.

Similar numerals referA to similar parts throughout the drawings. v

The phonograph shown in the drawings is 'of common construction. The casing 1 60ntains the driving mechanism, not shown,

which, by means of the belt 2 over the pulley 3, rotates the cylinder-record-mzmdrel 4. On the same shaft with the pulley 3 is fixed the spur gear 5, which meshes wlth the idler 6, which in turn rotates the spur gear 7. The spur gear 7 is fixed to the worm, which is journaled in the I brackets 9 and 9*. The guide bar 10 is also supported by the brackets 9 and 9, and thereon is slidably mounted the reproducer frame 11, to the lower part of which is attached the nut 12, which meshes with the worin 8. Thus, when the worm screw is turned, the reproducer moves parallel to the axis of the mandrel.

lVhen a cylinder record is operated on the mandrel, the .reproducer needle (not shown) is vibrated by its contact with the revolving record and sound waves are produced in the reproducer 11 from whence they are conveyed through the goose-neck .13 and the tone-arm 14 to the horn 14". The nut 12 can be thrown open or out of engagement with the Worm and the reproducer needle raised from the record, by slightly raising the controllin -lever 12,y thus simultaneously stopping t e endwise movement of the repro-- jointed bracket is employed, lwhich. includes the bearing frame-15 'which is jointed to the barsvl, w ich are hinged to the casing by the pivoted supports 17. On the front of the bearing frame is formed or connected the bifurcated foot 18, which is adapted to straddle the guide bar 10 and thus hold the jointed bracket in a rigid and elevated position.l

If` it is desired to. lay-cylinder records, the jointed bracket is oldedback out of thc way, as shown in Fig..3; but-,if disk records are to be played, it is brought upward and forward 'into an elevated,y position, and' the foot 18 is enged on the guide bar 10. Then the repr ucer, is moved toward the 'ointed 'bracket by lifting the lever 12", which eeps the' reproducen' out of action, and said lever is held out of action bydplqing it over the pin 18, whichis connecte to the foot 18.

vso

Then the shaft 19, to which is axially fixed the turn-table 20, is inserted through the hearing 21 Ain the bearing frame, and the lower end of the shaft is journaled 1n the step bearing 22 which is formed in the plate 23. This plate is formed as shown in Fig. 5, and its notched ends 24 embrace the brackets 9, which prevent any lateral movement.

Rotary motion is communicated to the turn-table 20 from the mandrel 4 by suitable gearing, the preferred form of which is illustrated. 0n the under side of the turntable is located the crown wheel 25 which engages the spur gear 2G, which tits snugl on the large end of the mandrel. It. wil be seen that when the' mandrel rotates, the gears 25 and 26 will impart motion to th turn-table.

Even though the jointed bracket is not held firmly in osition, or if it should be slightly out of `lts proper position, the spur gear. 26, on account of its wide face, will make allowance of any such irregularity and -will mesh -With the teeth of the crown wheel 'ust the same. The size of these gears is pre erably made such, that the two styles -1 of records can be played at substantially the saine speed, thus making it Aunnecessary-to change the speed adjustment.

By turning the thumb screw 27 the cylinder reproducer 11* can be removed from its frame, and the goose-neck 13 is then free toV be Withdrawn from the tone-arm. The disk fre'producer 28 is then firmly connected to the tone-arm by insertin its tubular shank 28'L into the tone-arm an engagingthe pin 28'" on the shank in the L-shaped s ot 14b in the tone-arm.

There is preferably a pivotal connection between the cose-neck and the cylinder reproducer an it-is sometimes desirable to remove only the goose-neck from the machine, and therefore it is made detachable from the reprodncer. This connection is shown in Figs. 6 and 7. The split tube 13l of the goose-neck is provided with an internal annular rib 30 which tits loosely in the annular 'groove 31 in the tube 31 of the -reproducer. On, the cose-neck are located the fixed collar 32, t e loose collar and the intervening coiled s ring 34, which is normally expanded, an its respective ends are attached to the collars. When the s ring is com ressed by sliding the loose colar upwar the split tube 13* is free to expend and the reproducer can be detached as shown in.

Fig. 6. On the turn-table is the usual covering of felt 20 and the centering pin 20", on which can be placed the disk record 29.

When these reparations are made, the machine is rea y to be started and it is operated in the usual manner. It is obvious that no skill is required and but little time is consumed in changing from one style rec- .ord to another;

Furthermore, the device can very easily be applied to any machine without requiring it to be sent to the factory. ,And it is evident that the use of the step bearing is not essential, although the same is preferred because its use renders unneces- 'sary the making of the jointed bracket and its connections strong enough and the bearing therein large enough to hold the axial shaft of the disk table Without a step bearling.
